'Ihis invention relates to an air cleaner and particularly to a constructionv adapted to clean or remove or precipitate foreign matter from l the air which is admitted into the fuel line of an A internal combustion engine for admixture with gasoline or the like.

It is particularly aimed to provide a novel construction which may be disassembled and in which the dust may be removed very rapidly 19 and expeditiously, and also a construction wherein there is dead air in the cleaning compartment to the end that the air will not be circulated by the suction of the engine to enhance the dust collecting function.

The more specific objects and advantages will become apparent from a consideration of the description following taken in connection with accompanying drawings illustrating an operativeI embodiment.

In said drawings:-

Figure 1 is a substantially central vertical sectional view through the improved cleaner,

Figure 2 is a horizontal sectional view taken on the line 2-2 of Figure 1,

Figure 3 is a vertical sectional view taken on the line 3-3 of Figure 2,

Figure 4 is substantially an inverted plan view of the cleaner taken on the line 4 4 of Figure 1,

Figure 5 is a cross sectional view taken on the line 5-5 of Figure 1,

Figure 6 is a detail sectionalview taken on the line 6-6 of Figure 2, and

Figure '7 is a sectional View taken on the line 7-7 of Figure 6.

' Referring specifically to the drawings, a suitable casing is provided as at A consisting of a base 19 and an inverted bell-shaped section 11 removably disposed thereon and engaging a rubber or other gasket 12, of annular form, located in a suitable groove 13 in the upper surface of base 10. Air to be cleaned enters the pipe 14 which extends through the base 10 and it leaves ina clean condition through a discharge pipe 15. The pipe 15 is connected in the fuel line of the internal combustion engine to the carburetor of which the air is supplied for admixture with the gasoline or other fuel, and hence the air is drawn through the pipe 14 and the entire device and discharged by the suction of the engine.

Within the casing are provided any desired number of cleaning compartments 16. Said compartments 16 are defined by rigid annular walls or rings 1'7 arranged in concentric relation as 55 shown in combination with bags 18. Bags 18,are

made of a suitable cloth or foraminous material as for instance muslin. Such bags may be of d iierent size meshes, if desired, and for instance with the meshes of the respective bags progressively decreasing in size from the smaller or in- 60. nermost bag to the outer or larger bag; The precipitated dust or foreign matter will collect in the compartments 16 on the base plate 10 and the same is adapted to be removed or to fall therefrom through openings 19 provided through said 65 base plate 10. Normally such openings 19 are closed by a closure or plate 20 which is removably clamped against the under surface of the plate 10, engaging rubber or other gaskets at- 21, preferably of annular or endless form, and disposed in grooves 22 in the base 10, and between the openings of the respective compartments or chambers 16, and another between the innermost row of openings and pipe 14. Swivel clamps or bars 23 engage'the plate 20 to normally hold 75 it air-tight in place but which plate may be lowered by sliding movement along the pipe 14 to enable discharge of dust or foreign matter; Such clamps 23 are pivoted on rods 24 depending from the base plate 10 and are held in 80 place through the tension of springs 26 on such rods, held in place by nuts 27 which are adjustable to vary the tension vof such springs. vThe clamps 23 of course are slidable longitudinally of the rods 24 against the tension of the springs 85 26 in the lowering of the closure plate 20.

The connection of the walls 17 to the base 10 and of the bags to the said walls is effected in 'an air-tight manner, so that there will be dead air in the chambers or compartments 16, as

shown at a, b, and c.

The dead air chambers a and b extend upwardly from the upper surface of base 10, to a point even with the upper edges Aof members 1'7.

The dead air chamber c extendsdownwardly and outwardly from the top of pipe 14 to the upper edge of the innermost member 17 as shown by dotted lines d. 'Ihus it will be seen that all of said chambers co-act in unison as receptacles, to receive the deposit and precipitation of the foreign matter. ,To this end, the lower edge of each wail 17 is removably seated on an annular rubber or other gasket 28, disposed in a groove 29 of the base 10, such gasket being grooved, as shown, if desired, to receive the Wall. The lower or open end of the bags 18 telescope over the exterior of the walls 17 and the air-tight connection is made by a cord 30 of textile material or the like, such cord and the adjacent portion of each bag being fully impregnated with shellac or equivalent sealing material. A skeleton supporting frame is disposed withineacli' bag and the same may consist of crossed U-Shaped rods 31 and 32 whose lower or free ends are secured to walls 17, by riveting, soldering. or in any other preferred manner.

Each bag and wall 17 is removable as a unit and is secured in place through the action of hold-down levers 33 pivoted to the base plate 10 as at 34, or by other suitable fastenings, not shown. Such levers carry lugs 35 which engage spring lugs 36 carried by the walls 17. 'I'he levers 33 and lugs 35 serve as latches to engage the l lugs 36, the spring action o1' the latter enabling them to yield and then to expand to hold the latches in locked position as shown in Figure 7 and also urge the members 17 into air-tight relation with the gasket 28.

The base 10 and bell 11 may be secured together in any suitable manner as by means of toggle bolts 37 pivoted at 38 on the base plate 10 and engaging in U-shaped lugs 39 on the bell 11, which are engaged by the nuts 40 oi' such bolts.

In operation we will assume that pipe 15 of the cleaner has been previously connected to the induction pipe of an internal combustion motor and that the motor has been set in motion. Due to the pumping action of the engine pistons, a stream of air will be caused to ow through the cleaners inlet pipe 14 into the innermost bag 18, thence the air will slowly lter through the meshes of said bag into the space between it and the adjacent bag; the larger portion of any dust` or foreign matter which may have been drawn into the inner chamber with the incoming air will have been iiltered out by the action of the meshes of the inner bag upon the air while it was passing therethrough, the foreign matter thus filtered out of the air stream falls by gravity into chamber c where it will remain until it is removed manually.

After the air stream has -passed through the innermost bag 18 into the space between it and its surrounding bag, it is drawn through the next bag and is further subjected to a cleaning action While passing through said bag into the space between said bag and the outermost bag. 'I'he action of the meshes of the last mentioned bag further removes some of the dirt from the air stream, which settles-through the space between said bags, into the dead air space b from whence it may be manually removed.

The air stream then is drawn through. the outer bag and a further illter cleaning effect is eilected by the'meshes of this outermost bag, the meshes of which, if desired, may be smaller than the meshes of the other mentioned bags, and thus be effective in removing the finest particles of dust from the air stream, this dust thus liinally removed will also find its way by the action of gravity into the dead airchamber a. It will be further noted that due to the larger space E between the outermost bag and its enclosing bell 11, the 'air stream which has successively passed through the filter members will be slowed down and a further and ilnal cleaning of the air stream will take place by the action of gravity, and to such a degree that the air as delivered to the engine cylinders will be ilt to 'use therein.

The construction enables the ready. and expeditious removal of the extracted dust and foreign matter simply by removing or lowering the closure 20, the dust or foreign matter falling through the openings 19. Also, all of the parts of the device may be readily disassembled through actuation of the various latches, clamps or the like.

From the foregoing it will be noted that I have providedl an air cleaner that employs a series filtering principle in combination with a gravity settling action principle. I am aware that air cleaners have been used in combination with internal combustion engines, but I am not aware that air cleaners employing the structure disclosed in my drawings has been used before me.
